Secure URL Embed

Use this option to securely embed dashboards where you can filter the data based on parameters that are encrypted (using your customer key). This ensures that the request is not tampered with.

Steps:

Contact us to obtain a customer key.

Use the key to AES encrypt your request parameters. Include contentFilters as a parameter (mandatory).

Link Expiry

You can also specify a time to expire for a given request for secure embedding, so that the link with the same parameters cannot be reused. To add an expiry, pass in the following two parameters to the request prior to the encryption routine: Current Epoch Time: _t Expiry in seconds: _ttl (default is 60 seconds if _t is present without _ttl).

Example url before passing it through the hashing/encryption routine: contentFilters=[{"fieldName":"opened","values":[1000],"operator":">"}]&_t=1537661183&_ttl=30
